제목 Physicochemical and electrochemical properties of carbon nanocoating on Ni0.8Co0.15Al0.05(OH)2 precursor using surfactant
초록 The LNCA(LiNi0.8Co0.15Al0.05O2) has stable layered structure comparing with LiNi0.8Co0.2O2for lithium ion battery. The carbon coating on the surface of LNCA stabilizes the layered structure and presents a good conductivity and low contamination. In order to coat carbon on the surface of LNCA, the NCA (Ni0.8Co0.15Al0.05(OH)2) precursor was coated with surfactant. Next, the NCA/C and lithium source were mixed for calcination. The FE-SEM and HR-TEM were used for For investigating morphology and size. The structure was analyzed by XRD. We measured the electrochemical performances of the LNCA/C as a cathode using A.C. impedance, CV, and charge-discharge performance.
